Inconel X-750 alloy is mainly a γ "[Ni3(Al, Ti, Nb)] phase aging strengthened nickel based superalloy, with good corrosion
resistance and oxidation resistance below 980℃, high strength below 800℃, and good relaxation resistance below 540℃. It also has good formability and weldability. The alloy is mainly used in the manufacture of plane springs and helical springs that are resistant to relaxation and require high strength for aircraft engines operating below 800 ° C. It can also be used to manufacture turbine turbine blades and other parts. The varieties available are sheet, strip, bar, forgings, rings, wire and tubing.
Pipe generally refers to the pipe fittings used to transport various fluids in the pipeline. Common cast iron pipe, steel pipe, non-ferrous metal pipe, non-metallic pipe, plastic pipe and so on. Generally, the pipe is usually round, and there are also shaped tubes made of non-circular cross sections. There are many materials for making pipes, and metals such as steel, iron and copper are commonly used.
Steel pipe is the most widely used pipe with high strength, smooth surface and good technology (can be welded, cut and bent). Steel pipes are divided into two categories: welded steel pipes and seamless steel pipes. Water and gas steel pipe is a kind of welded steel pipe with longitudinal straight weld, which is divided into ordinary type and reinforced type according to the thickness of the pipe wall, the caliber is generally 5 ~ 150 mm, and the nominal pressure is not more than 1.6 mpa. The two ends of this steel pipe are available with and without threads. The surface of the steel pipe also has two kinds of galvanized and non-galvanized. Galvanized steel pipe is commonly called white iron pipe, which is more corrosion resistant and is widely used in water supply pipes. The diameter of spiral welded steel pipe is generally 100 ~ 700 mm, mostly used for heating, gas and oil pipelines, and the largest diameter of welded steel pipe for long-distance transmission of oil and natural gas has exceeded 1500 mm. The wide range of seamless steel pipe materials and wall thickness is widely used in various pressure pipes, and the caliber is generally 4 to 630 mm. In addition to being used as pressure pipes in power engineering, chemical industry, petroleum industry and other sectors, seamless steel pipes are also important structural materials for aircraft, ships, drilling RIGS and bicycles.
